BACKGROUND

An area of ongoing research and development is systems and methods toprovide for accurate scoring of athletic events. More recently instantreplay has been instituted in various sports to allow officials toreview plays and calls made by the officials. However, in many sports,human scoring and officiating still produces a controversial margin oferror. With athletes pushing the envelope of human performance, itbecomes more difficult for humans to officiate and score athleticevents. There therefore exists the need for systems and methods thatfurther remove officiating and scoring duties away from humans inathletic events.

The foregoing examples of the related art and limitations relatedtherewith are intended to be illustrative and not exclusive. Otherlimitations of the relevant art will become apparent to those of skillin the art upon reading the specification and studying of the drawings.

SUMMARY

The following implementations and aspects thereof are described andillustrated in conjunction with systems, tools, and methods that aremeant to be exemplary and illustrative, not necessarily limiting inscope. In various implementations one or more of the above-describedproblems have been addressed, while other implementations are directedto other improvements.

Various implementations include systems and methods for scoring anathletic event based on changes in impedance in impedance-based impactmeasuring sporting equipment as a result of impacts delivered during theathletic event. In various implementations, a conductive material of aplurality of separate conductive materials are coupled to a firstparticipant, the conductive material configured to move when the firstparticipant delivers an impact to a second participant. Further, invarious implementation, an impedance-based impact sensing mechanismincluding an impedance changing mechanism that changes impedance as theconductive material is moved towards and away from the impedancechanging mechanism as the first participant delivers the impact. Invarious implementations, an impedance-based impact measuring scoringsystem determines that the impact occurred based on a change inimpedance in the impedance changing mechanism.

These and other advantages will become apparent to those skilled in therelevant art upon a reading of the following descriptions and a study ofthe several examples of the drawings.

DETAILED DESCRIPTION

FIG. 1 depicts a diagram 100 of an example of a system for scoring anathletic event using impedance-based impact measuring sportingequipment. The diagram 100 includes a computer-readable medium 102,impedance-based impact measuring sporting equipment 104, and animpedance-based impact measuring scoring system 106.

The impedance-based impact measuring sporting equipment 104 and theimpedance-based impact measuring scoring system 106 are coupled to eachother through the computer-readable medium 102. As used in this paper, a“computer-readable medium” is intended to include all mediums that arestatutory (e.g., in the United States, under 35 U.S.C. 101), and tospecifically exclude all mediums that are non-statutory in nature to theextent that the exclusion is necessary for a claim that includes thecomputer-readable medium to be valid. Known statutory computer-readablemediums include hardware (e.g., registers, random access memory (RAM),non-volatile (NV) storage, to name a few), but may or may not be limitedto hardware.

The computer-readable medium 102 is intended to represent a variety ofpotentially applicable technologies. For example, the computer-readablemedium 102 can be used to fonn a network or part of a network. Where twocomponents are co-located on a device, the computer-readable medium 102can include a bus or other data conduit or plane. Where a firstcomponent is co-located on one device and a second component is locatedon a different device, the computer-readable medium 102 can include awireless or wired back-end network or LAN. The computer-readable medium102 can also encompass a relevant portion of a WAN or other network, ifapplicable.

The computer-readable medium 102, the impedance-based impact measuringscoring system 106 and other applicable systems, or devices described inthis paper can be implemented as a computer system, a plurality ofcomputer systems, or parts of a computer system or a plurality ofcomputer systems. A computer system, as used in this paper, is intendedto be construed broadly. In general, a computer system will include aprocessor, memory, non-volatile storage, and an interface. A typicalcomputer system will usually include at least a processor, memory, and adevice (e.g., a bus) coupling the memory to the processor. The processorcan be, for example, a general-purpose central processing unit (CPU),such as a microprocessor, or a special-purpose processor, such as amicrocontroller.

The memory can include, by way of example but not limitation, randomaccess memory (RAM), such as dynamic RAM (DRAM) and static RAM (SRAM).The memory can be local, remote, or distributed. The bus can also couplethe processor to non-volatile storage. The non-volatile storage is oftena magnetic floppy or hard disk, a magnetic-optical disk, an opticaldisk, a read-only memory (ROM), such as a CD-ROM, EPROM, or EEPROM, amagnetic or optical card, or another form of storage for large amountsof data. Some of this data is often written, by a direct memory accessprocess, into memory during execution of software on the computersystem. The non-volatile storage can be local, remote, or distributed.The non-volatile storage is optional because systems can be created withall applicable data available in memory.

Software is typically stored in the non-volatile storage. Indeed, forlarge programs, it may not even be possible to store the entire programin the memory. Nevertheless, it should be understood that for softwareto run, if necessary, it is moved to a computer-readable locationappropriate for processing, and for illustrative purposes, that locationis referred to as the memory in this paper. Even when software is movedto the memory for execution, the processor will typically make use ofhardware registers to store values associated with the software, andlocal cache that, ideally, serves to speed up execution. As used herein,a software program is assumed to be stored at an applicable known orconvenient location (from non-volatile storage to hardware registers)when the software program is referred to as “implemented in acomputer-readable storage medium.” A processor is considered to be“configured to execute a program” when at least one value associatedwith the program is stored in a register readable by the processor.

In one example of operation, a computer system can be controlled byoperating system software, which is a software program that includes afile management system, such as a disk operating system. One example ofoperating system software with associated file management systemsoftware is the family of operating systems known as Windows® fromMicrosoft Corporation of Redmond, Wash., and their associated filemanagement systems. Another example of operating system software withits associated file management system software is the Linux operatingsystem and its associated file management system. The file managementsystem is typically stored in the non-volatile storage and causes theprocessor to execute the various acts required by the operating systemto input and output data and to store data in the memory, includingstoring files on the non-volatile storage.

The bus can also couple the processor to the interface. The interfacecan include one or more input and/or output (I/O) devices. The I/Odevices can include, by way of example but not limitation, a keyboard, amouse or other pointing device, disk drives, printers, a scanner, andother I/O devices, including a display device. The display device caninclude, by way of example but not limitation, a cathode ray tube (CRT),liquid crystal display (LCD), or some other applicable known orconvenient display device. The interface can include one or more of amodem or network interface. It will be appreciated that a modem ornetwork interface can be considered to be part of the computer system.The interface can include an analog modem, isdn modem, cable modem,token ring interface, satellite transmission interface (e.g. “directPC”), or other interfaces for coupling a computer system to othercomputer systems. Interfaces enable computer systems and other devicesto be coupled together in a network.

The computer systems can be compatible with or implemented as part of orthrough a cloud-based computing system. As used in this paper, acloud-based computing system is a system that provides virtualizedcomputing resources, software and/or information to client devices. Thecomputing resources, software and/or information can be virtualized bymaintaining centralized services and resources that the edge devices canaccess over a communication interface, such as a network. “Cloud” may bea marketing term and for the purposes of this paper can include any ofthe networks described herein. The cloud-based computing system caninvolve a subscription for services or use a utility pricing model.Participants can access the protocols of the cloud-based computingsystem through a web browser or other container application located ontheir client device.

A computer system can be implemented as an engine, as part of an engine,or through multiple engines. As used in this paper, an engine includesat least two components: 1) a dedicated or shared processor and 2)hardware, finnware, and/or software modules that are executed by theprocessor. Depending upon implementation-specific or otherconsiderations, an engine can be centralized or its functionalitydistributed. An engine can include special purpose hardware, firmware,or software embodied in a computer-readable medium for execution by theprocessor. The processor transforms data into new data using implementeddata structures and methods, such as is described with reference to theFIGURES in this paper.

The engines described in this paper, or the engines through which thesystems and devices described in this paper can be implemented, can becloud-based engines. As used in this paper, a cloud-based engine is anengine that can run applications and/or functionalities using acloud-based computing system. All or portions of the applications and/orfunctionalities can be distributed across multiple computing devices,and need not be restricted to only one computing device. In someembodiments, the cloud-based engines can execute functionalities and/ormodules that end users access through a web browser or containerapplication without having the functionalities and/or modules installedlocally on the end-users' computing devices.

As used in this paper, datastores are intended to include repositorieshaving any applicable organization of data, including tables,comma-separated values (CSV) files, traditional databases (e.g., SQL),or other applicable known or convenient organizational formats.Datastores can be implemented, for example, as software embodied in aphysical computer-readable medium on a general- or specific-purposemachine, in firmware, in hardware, in a combination thereof, or in anapplicable known or convenient device or system. Datastore-associatedcomponents, such as database interfaces, can be considered “part of’ adatastore, part of some other system component, or a combinationthereof, though the physical location and other characteristics ofdatastore-associated components is not critical for an understanding ofthe techniques described in this paper.

Datastores can include data structures. As used in this paper, a datastructure is associated with a particular way of storing and organizingdata in a computer so that it can be used efficiently within a givencontext. Data structures are generally based on the ability of acomputer to fetch and store data at any place in its memory, specifiedby an address, a bit string that can be itself stored in memory andmanipulated by the program. Thus, some data structures are based oncomputing the addresses of data items with arithmetic operations; whileother data structures are based on storing addresses of data itemswithin the structure itself. Many data structures use both principles,sometimes combined in non-trivial ways. The implementation of a datastructure usually entails writing a set of procedures that create andmanipulate instances of that structure. The datastores, described inthis paper, can be cloud-based datastores. A cloud-based datastore is adatastore that is compatible with cloud-based computing systems andengines.

In a specific implementation, the impedance-based impact measuringsporting equipment 104 functions to detect characteristics associatedwith an impact. In detecting characteristics associated with an impact,the impedance-based impact measuring sporting equipment can include oneor a plurality of sensors used in detecting characteristics associatedwith an impact. Sensors included as part of the impedance-based impactmeasuring sporting equipment 104 can include any combination ofimpedance based impact sensing mechanisms, gyroscopes, and/or inertialmeasurement units (hereinafter referred to as IMUs). Depending uponimplementation-specific or other considerations, sensors included aspart of the impedance-based impact measuring sporting equipment 104 canbe used to measure changes in rotation and location of a participant inan athletic event. Changes in rotation and location, as measured bysensors included as part of the impedance-based impact measuringsporting equipment 104 can be used to measure impacts or magnitudes offorces of impacts, and/or score an athletic event. Further dependingupon implementation-specific or other considerations, sensors includedas part of the impedance-based impact measuring sporting equipment 104can be arranged in a sensor matrix.

In a specific implementation, the impedance-based impact measuringsporting equipment 104 includes an outer layer of a syntheticelastomeric polymer. Sensors can be imbedded in the impedance-basedimpact measuring sporting equipment. Depending uponimplementation-specific or other considerations, in manufacturing theimpedance-based impact measuring sporting equipment, sensors can beembedded into a synthetic elastomeric polymer layer in a gel foam. Inoperation of the impedance-based impact measuring sporting equipment104, an impact delivered to the impedance-based impact measuringsporting equipment 104 causes the synthetic elastomeric polymer toharden, thereby dispersing energy delivered through the impact across anouter surface or a portion of an outer surface of the impedance-basedimpact measuring sporting equipment 104.

In a specific implementation, the impedance-based impact measuringsporting equipment 104 includes one or a plurality of impedance-basedimpact sensing mechanisms that function to detect an impact and, e.g., amagnitude of a force of the impact. Depending uponimplementation-specific or other considerations, the impedance-basedimpact measuring sporting equipment 104 can include a set of separateimpedance-based impact sensing mechanisms positioned on various portionsof a body of a participant using the impedance-based impact measuringsporting equipment 104, or on applicable inanimate objects. Inpositioning a set of separate impedance-based impact sensing mechanismson a participant, a portion of the body of the participant of theimpedance-based impact measuring sporting equipment 104 where impactoccurs can be detected with accuracy sufficient to make thedetermination useful when scoring an athletic event, or for otherapplicable purposes where determining the location of a strike isuseful.

In a specific implementation, an impedance-based impact sensingmechanism included as part of the impedance-based impact measuringsporting equipment 104 includes an impedance changing mechanism thatchanges impedance when a conductive element is moved relative to theimpedance changing mechanism and/or when the conductive element comesinto contact with the impedance changing mechanism. An impedancechanging mechanism can include conductive coils that extend over an areaor part of an area of the impedance-based impact sensing mechanism. Aregulated AC can be passed through conductive coils that form part of animpedance changing mechanism to form a magnetic field. As a result, whena conductive material moves towards or away from conductive coils of animpedance charging mechanism, currents of varying sizes, e.g. “eddycurrents”, are induced in the conductive coils that flow opposite thedirection that the regulated AC passes through the conductive coils.Currents of varying sizes, induced in an impedance changing mechanism asa conductive material moves towards and away from the impedance changingmechanism, produce counter forces against an original current, e.g.regulated AC, passed through the impedance changing mechanism. As aresult, impedance characteristics of an impedance changing mechanismchange, e.g. lead to an increased impedance of the impedance changingmechanism, as a conductive material moves towards and away from theimpedance changing mechanism.

In a specific implementation, when a metallic material worn by thestriker or striking object approaches an electrically conductive coilwith a reference inductance that is included as part of an impedancechanging mechanism included as part of the impedance-based impactmeasuring sporting equipment. The approaching metal changes theinductive value of the coil due to Eddy current effect. This propertycan be used to identify the source of the strike which then can be usedto qualify an impact of the strike.

In a specific implementation, an impedance-based impact sensingmechanisms included as part of the impedance-based impact measuringsporting equipment 104 includes or is coupled to a digital converter anda data processing system, such as a microprocessor. As a conductivematerial moves towards an impedance changing mechanism of animpedance-based impact sensing mechanism included as part of theimpedance-based impact measuring sporting equipment 104, impedancecharacteristics of the impedance changing mechanism change. A digitalconverter included as part of or coupled to the impedance-based impactsensing mechanism generates signals based on changes in impedance in theimpedance changing mechanism that can be processed by the dataprocessing system part of or coupled to the impedance-based impactsensing mechanism. Signals generated and processed based on changes inimpedance in the impedance changing mechanism can be used to determineimpact to an impedance-based impact sensing mechanism of theimpedance-based impact measuring sporting equipment 104 and a magnitudeof a force of the impact to the impedance-based impact sensingmechanism.

In a specific implementation, the impedance-based impact measuringsporting equipment 104 includes a plurality of separate impedancechanging mechanisms that have different impedance characteristics. Inhaving different impedance characteristics, separate impedance changingmechanisms of the impact measuring sporting equipment can bedistinguished from each other using impedance and changing impedancewithin the separate impedance changing mechanisms. Depending uponimplementation-specific or other considerations, in having differentimpedance characteristics, the separate impedance changing mechanismscan change impedance at different rates when a conductive material ismoved towards and away from each separate impedance changing mechanismat the same rate. Further depending upon implementation-specific orother considerations, in having different impedance characteristics, theseparate impedance changing mechanisms can have different nativeimpedances, a native impedance, as used in this paper, being animpedance of an impedance changing mechanism when a specific current isrun through the impedance changing mechanism without the influence of aconductive material moved in proximity to the impedance changingmechanism. Different impedance characteristics of separate impedancechanging mechanisms can be achieved by designing impedance changingmechanisms according to applicable techniques for creating differentimpedance characteristics in separate impedance changing mechanisms,such as including varying numbers of coils or coils of varying sizes ofa conductive material in separate impedance changing mechanisms. Increating impedance-based impact sensing mechanisms that have differentimpedance characteristics, different parts of the body of a secondparticipant or an applicable inanimate object receiving an impact of afirst participant using the impedance-based impact measuring sportingequipment 104 can be detected. For example, based on different impedancecharacteristics of impedance-based impact sensing mechanisms of theimpedance-based impact measuring sporting equipment 104 can be used todetermine whether an impact is delivered by a first participant to thechest or the arm of a second participant.

In a specific implementation, the impedance-based impact measuringsporting equipment 104 includes a conductive material worn by a firstparticipant delivering an impact to a second participant (or inanimateobject). For example, the impedance-based impact measuring sportingequipment 104 can include a conductive material that is positioned on ahand or foot (or other part of the body, such as the elbow, shin, knee,etc.; or on a portion of a weapon) of a first participant using theimpedance-based impact measuring sporting equipment 104 to allow animpact delivered against a second participant using of theimpedance-based impact measuring sporting equipment 104 to be detectedand characteristics, such as the magnitude of the force of the impact,to be determined. The conductive material can be placed in sportingequipment and apparel such as boxing gloves, MMA gloves, gloves, socks,sneakers, shoes, mittens, shirts, pants, shorts, elbow guards, helmets,shin guards, knee pads, striking garments, striking apparel, strikingequipment, swords, weapons, and combinations thereof.

In a specific implementation, the impedance-based impact measuringsporting equipment 104 includes separate conductive materials thatchange impedance differently in impedance-based input sensing mechanismsof a participant wearing the impedance-based input sensing mechanisms.In changing impedances in impedance-based sensing mechanismsdifferently, separate conductive materials in the impedance-based impactmeasuring sporting equipment 104, can be of varying sizes or of varyingmaterials. Specific conductive materials in the impedance-based impactmeasuring sporting equipment 104 can be of varying sizes or varyingmaterials according to a position of specific conductive materials on afirst participant using the impedance-based impact measuring sportingequipment 104 to deliver an impact to a second participant (or inanimateobject) of the impedance-based impact measuring sporting equipment 104.For example, a conductive material on the foot of a first participant ofthe impedance-based impact measuring sporting equipment can be of adifferent size of a conductive material on a hand of the firstparticipant, allowing an impact delivered by the foot of the firstparticipant to be differentiated and subsequently determined from animpact delivered by the hand of the first participant.

In a specific implementation, the impedance-based impact measuringscoring system 106 functions to score, at least in part, an athleticevent in which the impedance-based measuring sporting equipment 104 isused based on changing impedances of impedance changing mechanisms as aresult of impact. In scoring, at least in part, an athletic event,depending upon implementation-specific or other considerations, theimpedance-based impact measuring scoring system 106 determines amagnitude of a force of an impact to the impedance-based impactmeasuring sporting equipment 104 using a change of impedance in animpedance changing mechanism. Further depending uponimplementation-specific or other considerations, in scoring, at least inpart, an athletic event, the impedance-based impact measuring scoringsystem 106 can determine a portion of a second participant using theimpedance-based impact measuring sporting equipment 104 to which impactis delivered using a change in impedance in an impedance changingmechanism. Depending upon implementation-specific or otherconsiderations, in scoring, at least in part, an athletic event, theimpedance-based impact measuring scoring system 106 can determine aportion of a first participant using impedance-based impact measuringsporting equipment 104 that impacts a second participant usingimpedance-based impact measuring sporting equipment 104 utilizing achange in impedance in an impedance changing mechanism. Further, inscoring, at least in part, an athletic event, depending uponimplementation-specific or other considerations, the impedance-basedimpact measuring scoring system 106 can score the athletic event basedon a magnitude of a force of a delivered impact, a portion of a secondparticipant to which the impact is delivered, or a portion of a firstparticipant that delivers the impact to the second participant.

In the example system shown in FIG. 1, the impedance-based impactmeasuring scoring system 106 includes an impact force determinationsystem 108, an impact location determination system 110, an impactdelivery determination system 112, and a scoring system 114. In aspecific implementation, the impact force determination system 108functions to determine a magnitude of a force delivered to a secondparticipant based on a change in impedance in impedance changingmechanisms in the impedance-based impact measuring sporting equipment104. In determining a magnitude of a force of impact based on a changein impedance in impedance changing mechanisms, the impact forcedetermination system 108 can determine the magnitude of the force of theimpact based on the rate at which impedance changes in impedancechanging mechanisms as a result of impact. For example, if impedancechanges in an impedance changing mechanism at a faster rate as a resultof an impact, than a change in impedance in the impedance changingmechanism as a result of a previous impact, then the impact forcedetermination system 108 can determine that a magnitude of a force ofthe impact is greater than a magnitude of a force of the previousimpact. In determining a magnitude of a force of an impact based onrates at which impedance changes in an impedance changing mechanism inthe impedance-based impact measuring sporting equipment 104, the impactforce determination system 108 can determine the magnitude of the forceby comparing the rate at which impedance changes in the impedancechanging mechanism to impedance changing rate data for the impedancechanging mechanism. Impedance changing rate data for an impedancechanging mechanism of the impedance-based impact measuring sportingequipment 104 can be predetermined and specify magnitudes of forces ofimpact corresponding to specific rates at which impedance changes in theimpedance changing mechanism.

In a specific implementation, the impact location determination system110 functions to determine a portion of a second participant (orinanimate object) of the impedance-based impact measuring sportingequipment 104 at which an impact occurs. In determining a portion of asecond participant of the impedance-based impact measuring sportingequipment 104 at which an impact occurs, the impact locationdetermination system 110 can determine the portion of the secondparticipant based on impedance characteristics specific to an impedancechanging mechanism positioned on the body of the second participant. Forexample, the impact location determination system 110 can determine thatan impact occurs in the chest of a second participant usingimpedance-based impact measuring sporting equipment 104 based onimpedance characteristics of specific impedance changing mechanismsincluded as part of the impedance-based impact measuring sportingequipment 104. Depending upon implementation-specific or otherconsiderations, the impact location determination system 110 candetermine a specific impedance changing mechanism on a secondparticipant based on rates at which impedance in the impedance changingmechanisms changes when a conductive material is moved towards and awayfrom the impedance changing mechanism. Further depending uponimplementation-specific or other considerations, the impact locationdetermination system 110 can determine a specific impedance changingmechanism based on a native impedance of the specific changing mechanismincluded as part of the impedance-based impact measuring sportingequipment 104.

In a specific implementation, the impact delivery determination system112 functions to determine a portion of a first participant using theimpedance-based impact measuring sporting equipment 104 that delivers animpact to a second participant using the impedance-based impactmeasuring sporting equipment 104. For example, the impact deliverydetermination system 112 can determine that an impact is delivered by afoot or a hand of a first participant. In determining a portion of afirst participant that delivers an impact, the impact deliverydetermination system 112 can use impact delivery characteristics data ofa first participant using the impedance-based impact measuring sportingequipment 104. Impact delivery characteristics data of a firstparticipant using the impedance-based impact measuring sportingequipment 104 can specify a rate at which impedance changes in impedancechanging mechanisms as a result of conductive materials positioned atdifferent position on a first participant being moved towards and awayfrom the impedance changing mechanisms. Specifically, impedance deliverycharacteristics data are different for conductive materials of differentsizes or materials that are positioned at different portion of aparticipant, e.g. a foot or a hand of the participant. Using a rate atwhich impedance changes in an impedance changing mechanism of a firstparticipant using the impedance-based impact measuring sportingequipment 104 as a result of an impact to the impedance changingmechanism, and impact delivery characteristics, the impact deliverydetermination system 112 can determine a portion of a first participantthat delivers the impact to a second participant. For example, theimpact delivery determination system 112 can determine, based on therate at which impedance changes in an impedance changing mechanism andimpact delivery characteristics, that a foot of a first participantdelivered impact to a second participant using the impedance-basedimpact measuring sporting equipment 104.

In a specific implementation, the scoring system 114 functions to scorean athletic event in response to impacts received and delivered bywearers of the impedance-based impact measuring sporting equipment. Forexample, the scoring system 114 can score an athletic event based onwhere an impact is received, a magnitude of a force of the impact,and/or a portion of a first participant that delivers the impact.Further, the scoring system 114 can score an athletic event based onimpact scoring data for an athletic event. Impact scoring data for anathletic event can specify how to score, e.g. a number of points toaward a first participant, based on where an impact is delivered, amagnitude of a force of the impact, a portion of a user that deliversthe impact, or other discernible factors.

In a specific implementation, the scoring system 114 can score anathletic event based on impact scoring data and a magnitude of a forceof a delivered impact, as determined by the impact locationdetermination system 108. Specifically, impact scoring data can specifyto award a specific number of points based on a magnitude of a force ofa delivered impact. As a result, the scoring system 114 can award anumber of points as specified by impact scoring data to a firstparticipant who delivers an impact based on a magnitude of a force ofthe impact, as determined by the impact force determination system 108.

In a specific implementation, the scoring system 114 can score anathletic event based on impact scoring data and a portion of a secondparticipant to which an impact is delivered, as determined by the impactlocation determination system 110. For example, impact scoring data canspecify to award a specific number of points based on a portion of asecond participant to which an impact is delivered, e.g. award morepoints if an impact is delivered to a chest of a second participant asopposed to a leg. As a result, the scoring system 114 can award a numberof points as specified by the impact scoring data to a first participantwho delivers an impact based on a portion of a second participant towhich the impact is delivered, as determine d by the impact locationdetermination system 110.

In a specific implementation, the scoring system 114 can score anathletic event based on impact scoring data and a portion of a firstparticipant that delivers an impact to a second participant, asdetermine d by the impact delivery determination system 112. Forexample, impact scoring data can specify to award a specific number ofpoints based on a portion of a first participant that delivers an impactto a second participant, e.g. award more points if an impact isdelivered by the foot of a first participant as opposed to a hand of thefirst participant. As a result, the scoring system 114 can award anumber of points as specified by the impact scoring data to a firstparticipant who delivers an impact based on a portion of the firstparticipant that delivers the impact to a second participant, asdetermine d by the impact delivery determination system 112.

FIG. 10 depicts a diagram 1000 of an example of impedance-based impactmeasuring sporting equipment. Depending upon implementation-specific orother considerations, the impedance-based impact measuring sportingequipment can include systems and designs detailed in U.S. Pat. No.7,891,231. A metallic fiber cloth has been added to the target area onthe second participant's protective garment (2). The inductive sensorcoil embedded in the first participant's glove (1) allows thetransmitter to detect contact with the metallic fiber cloth area,tagging the related impact as a punch technique. The impact signal maythen be modified or given a unique set of criteria for qualification.Alternatively or in addition, the first participant's glove can beconfigured to enable determining whether the strike landed was a punchor, e.g. a palm strike using one or more inductive sensor coils.Alternatively or in addition, the first participant's foot ware can beconfigured to enable determination of a kick.

FIG. 11 depicts a diagram 1100 of an example of a system used to measureacceleration of a participant in an athletic event. Depending uponimplementation-specific or other considerations, the example systemshown in FIG. 11 can be included as part of an applicable device orsystem using in scoring an athletic event, such as the impedance-basedimpact measuring sporting equipment described in this paper, and/or theimpedance-based impact measuring scoring systems described in thispaper. The example system shown in FIG. 11 includes a computer-readablemedium 1102, an acceleration sensor 1104, a threshold setting datastore1106, and an acceleration threshold determination system 1108. In theexample system shown in FIG. 11, the acceleration sensor 1104, thethreshold setting datastore 1106, and the acceleration determinationsystem 1108 are coupled to each other through the computer-readablemedium 1102.

In a specific implementation, the acceleration sensor 1104 functionsaccording to an applicable sensor for measuring acceleration of aparticipant in an athletic event. The acceleration sensor 1104 caninclude one or a plurality of acceleration sensors that work together.Depending upon implementation-specific or other considerations, theacceleration sensor 1104 can include one of or an applicable combinationof accelerometers, and/or IMUS. The acceleration sensor 1104 canfunction to measure acceleration of a participant in an athletic eventas impacts are delivered to the participant.

In a specific implementation, the threshold setting datastore 1106functions to store threshold accelerations for an acceleration sensor1104. Threshold accelerations stored in the threshold setting datastore1106 can by specific to acceleration sensors, whereby differentacceleration sensors have different acceleration thresholds. Dependingupon implementation-specific or other considerations, accelerationsensors can have different acceleration thresholds based oncorresponding positions of the acceleration sensors on a participant.Threshold accelerations can be used to differentiate between differentmoves performed during an athletic event and different impacts that arereceived during an athletic event. For example, if an acceleration, asdetermined by an acceleration sensor, exceeds a first accelerationthreshold, then it can be determined that a specific move was executedor an impact was received that corresponds to the first accelerationthreshold during an athletic event.

In a specific implementation, the acceleration threshold determinationsystem 108 functions to determine whether an acceleration sensed by anacceleration sensor on a participant of an athletic event exceeds anacceleration threshold for the acceleration sensor. If an accelerationis determined by the acceleration threshold determination system 1108 toexceed an acceleration threshold, then the acceleration thresholddetermination system 1108 can store the acceleration value of theacceleration determined to exceed the acceleration threshold. Dependingupon implementation-specific or other considerations, the accelerationthreshold determination system 1108 can send an acceleration value of anacceleration that is determined to exceed an acceleration threshold foran acceleration sensor to an applicable system for scoring an athleticevent, such as the impedance-based impact measuring scoring systemsdescribed in this paper. An acceleration value sent by the accelerationthreshold determination system 1108 can be used to score an athleticevent by an applicable scoring system to which the acceleration value issent. Further depending upon implementation-specific or otherconsiderations, the acceleration threshold determination system 1108 canbe configured to record all acceleration values of accelerationsdetermined by an acceleration sensor, regardless of whether theaccelerations surpass an acceleration threshold. Acceleration valuesrecorded by acceleration threshold determination system 1108 can furtherbe used to score an athletic event, e.g. in the event of a tie in theathletic event.

FIG. 12 depicts a flowchart 1200 of an example of a method for scoringan athletic event using acceleration thresholds for an accelerationsensor. The flowchart 1200 begins at module 1202, where an accelerationthreshold is set for an acceleration sensor. An acceleration thresholdcan be an acceleration value that corresponds to a particular move thatis performed during an athletic event or an impact that is delivered asa result of performance of the particular move during the athleticevent. An acceleration threshold can be uniquely associated with aparticular acceleration sensor. Depending upon implementation-specificor other considerations, a particular acceleration sensor can havemultiple acceleration thresholds associated with the particularacceleration sensor.

The flowchart 1200 continues to module 1204 where an acceleration of aparticipant is detected using the acceleration sensor. An accelerationof a participant detected by the acceleration sensor can be a result ofanother participant performing a particular move or delivering an impactduring an athletic event.

The flowchart 1200 continues to decision point 1206, where it isdetermined whether the acceleration, detected at module 1204 by theacceleration sensor, exceeds an acceleration threshold for theacceleration sensor. If it is determine d at decision point 1206 thatthe acceleration does not exceed the acceleration threshold, then theflowchart 1200 continues back to module 1204 where an acceleration of aparticipant is detected using the acceleration sensor. Optionally, anacceleration value of an acceleration that does not exceed anacceleration value of the acceleration sensor can be recorded and laterused to score an athletic event, e.g. in the event of a tie break.

If it is determined at decision point 1206, that the accelerationexceeds the acceleration threshold, then the flowchart continues tomodule 1208. At module 1208, the flowchart 1200 includes sending anacceleration value of the acceleration to an applicable system forscoring an athletic event, such as the impedance-based impact measuringscoring systems described in this paper.
